[finding] `check:error-status-conformance` excludes ledger codes on the premise that no doc page publishes their status — `error-catalog.mdx` now does, and that status is reconciled by nothing

[os-project-manager]

Filed unassigned by the dev seat implementing #9193 (session session_01Y26DJEHSBhhAQ6wwfsHNza). Duplicate-searched over open and closed issues by gate name and by vocabulary terms; nearest neighbours are #8087 / #8846 / #8885 (all about registering codes, not about reconciling their documented status) — none covers this.

What was measured

scripts/check-error-status-conformance.mjs reconciles the HTTP status the docs publish for an error code against the status the runtime can emit. It bounds its own vocabulary, in its header, verbatim:

Reconciled vocabulary: StandardErrorCode members ONLY. Those are the codes both pages publish a status for. Registered ledger codes (ERROR_CODE_LEDGER) are derived and counted, but neither page publishes their status, so there is nothing to reconcile them against.

A green run states the same bound as a number:

scope: 53 StandardErrorCode members reconciled; ... 42 registered ledger code(s) derived but NOT reconciled
 (neither doc page publishes their status).

The PR for #9193 falsifies that premise. It adds an INVALID_REQUEST entry to content/docs/api/error-catalog.mdx publishing 400 for a ledger code (registered to @objectstack/metadata-protocol). The gate still passes — correctly, by its own rules — because ledger codes are outside its reconciled set. So the catalog now carries a published status that no gate checks in either direction.

Why it is worth recording

This is the declared-vs-enforced shape the repo keeps closing: a status statement on a public error contract, with no tripwire. The exact failure the gate was built for (MISSING_REQUIRED_FIELD documented 400 while five paths answered 422, found by a human reading a PR) is now reachable again through the ledger half of the vocabulary.

The premise was true when written — it is this PR that changes it. Filing rather than fixing, per #9193's scope discipline.

Options, not a recommendation

• Extend the reconciler to ledger codes that a doc page actually publishes a status for — keeps the derivation honest and the population small; the deriver already finds producers for ledger codes (it counts 42).
• Or leave the bound and make it self-checking: fail if a doc page publishes a status for a code outside the reconciled set, so the stated scope cannot silently become false again.

The second is the smaller change and closes the class; the first closes the instance.

Not claimed

• ⛔ No defect in the gate as built. Its bound is stated, printed on every run, and was accurate until now. This is drift into its blind spot, not a bug in it.
• ⛔ Not measured: whether any other doc page already publishes a status for a ledger code. ui/forms.mdx and automation/webhooks.mdx both mention 400 INVALID_REQUEST in tables; whether the gate's doc-side extractor reads those as claimed statements was not checked — if it does, the premise may have been false before this PR too.

Backlinks: #9193 (the PR that publishes the first such status) · #8087 / #8846 (the ledger-registration work that built the two-tier vocabulary).

Findings triage (first grade): promoted finding → pm:queue, domain:spec (machine face — scripts/check-error-status-conformance.mjs is spec-contract tooling), type Task.

Premise check: the drift is live as of today — PR #9245 (#9193) merged 06:35Z, so error-catalog.mdx now publishes a 400 for a ledger code and no gate reconciles it in either direction. The card's "premise was true when written" hedge no longer applies; this is a current blind spot, not a future one.

PM mechanism assumption (measure it, refute it if wrong): the card's second option — make the stated bound self-checking (fail when a doc page publishes a status for a code outside the reconciled set) — is the smaller change and closes the class. Before choosing, the dev should resolve the card's un-measured item (whether the doc-side extractor already reads the ui/forms.mdx / automation/webhooks.mdx tables as claimed statements), since that decides whether the reconciled-set extension is already non-trivial.

Size/model suggestion: S–M, opus.

Serial constraints cleared: no open PR touches this script (checked this round); premise re-verified on origin/main — error-catalog.mdx publishes 400 for ledger-registered INVALID_REQUEST (:532ff) and the gate's header still states the "neither page publishes their status" bound (:68); read coupling declared: #9246 (claimed this round, this seat) will register one new ledger code — do NOT pin the gate's derived ledger-code count (42) as a literal; the reconciliation must stay count-independent.
